Introduction: The capacity to perform physical exercise has been of paramount importance in the continuous process of animals’ adaptation to the environment throughout evolution. When challenged with any physical task‚ the human body responds through a series of integrated changes in function that involve most‚ if not all‚ of its physiological systems. Movement requires activation and control of the musculoskeletal system; the cardiovascular and respiratory systems provide the ability to

The cell is one of the most basic units of life. There are millions of different types of cells. There are cells that are organisms onto themselves‚ such as microscopic amoeba and bacteria cells. And there are cells that only function when part of a larger organism‚ such as the cells that make up your body. The cell is the smallest unit of life in our bodies. In the body‚ there are brain cells‚ skin cells‚ liver cells‚ stomach cells‚ and the list goes on. All of these cells have unique functions

Introduction: Crayfish also known as Procambarus clariia are classified as a decapod crustaceans related to lobsters‚ crabs‚ and shrimp. They breathe through the gills as they are aquatic animals but they can survive for short time outside the water. They have a hard‚ calcified exoskeleton that must be shed as they grow. In front of the first abdominal segment locates crayfish heart in the dorsal portion of cephalothorax. Crayfish are poikilothermic as their internal temperature is proportional
